The TS-100 Air-Powered Speaker Stand (Patent Pending) lifts 50 lbs. for you! Our gas spring is under a 50 lb. preload when the speaker is safely loaded on the stand, turn the telescoping knob and raise any speaker weighing less than 50 lbs. with zero effort on your part. If your speaker is over 50 lbs, marvel at how little effort it takes to raise the speaker to the proper height. TS-100?s internal shock holds the speaker weight under a neutral load, reducing the lift load by 75% on average. Simply turn the telescoping knob and the TS-100 assists in smoothly raising and lowering heavy loads with minimal effort. Larger diameter, anodized tubing and metal reinforced clamps securely support more weight than other stands.
